Phoenix -- The Moneyball target definitely appears to be relievers this season: The A's, who made three significant bullpen additions during the winter and picked up numerous other relief candidates, claimed left-hander Joe Saveryoff waivers from the Phillies on Monday.

Savery, 28, did some solid work for Philadelphia last season, limiting opponents to a .205 average. He had a 3.15 ERA and two saves in 18 appearances, but the Phillies designated the 2007 first-round pick for assignment on Sunday to make room for starter A.J. Burnett.

"Acquiring Joe allows us to add more depth and flexibility from the left side to our bullpen," assistant general manager David Forstsaid in an e-mail. "He's pitched very well since converting to a relief role a few years ago and will get a long look here."

In a small sample size, Savery had some real reverse splits last year, with left-handed hitters batting .409 against him, right-handers .118. Nevertheless, he is likely to vie with Fernando Abad (acquired from Washington in November) for the second lefty spot in the bullpen. Savery has an option remaining. Abad does not, giving Abad one possible edge.

To make room for Savery on the 40-man roster, the A's moved left-hander Eric O'Flahertyto the 60-day disabled list. O'Flaherty, one of those major bullpen additions, along with closer Jim Johnsonand setup man Luke Gregerson, is not expected to pitch with Oakland until midseason after he had Tommy John surgery in May.

Savery, who went to Rice, will arrive in camp Tuesday and join the A's workout Wednesday.

Now get a Derrick: The A's might be setting a record for most ways to spell one name in big-league camp this spring, with catcher Derek Norris, first baseman Daric Bartonand non-roster pitcher Deryk Hooker.

"That's a new one," said reliever Sean Doolittle, who deals with unusual spellings of his own first name. "And I'd never seen a Daric before I came here. The cool new thing is apostrophes; maybe we can get a D'ric."

In his 10th spring with the A's, Barton arrived to find his name misspelled on one team schedule.

"I've given up. I have to spell it for people all the time," Barton said. "Now I just let them spell it however they want. But no one will ever guess D-E-R-Y-K."

"My mom just picked it out, and the spelling is unusual," said Hooker, 24, who signed as a minor-league free agent. "I have to correct it a lot."

"There are probably 15 ways to spell it, but I've never seen that one," Norris said. "You can switch the A and the E any way - but a Y?"

Doolittle has one suggestion for Derek and the Homonyms.

"Derek Jeter will be on his farewell tour this year," he said. "Maybe they can grab him for a group photo."

Briefly: Doolittle threw a bullpen session for the first time since straining his right calf muscle last week, and it went well. "I'm really pleased with how things feel," he said. ... Like last year, the A's won't have an intrasquad game before spring games begin Feb. 26. "We're not going to add a game just to add a game," manager Bob Melvinsaid. "We have 162 regular-season games, 30 during the spring. We have more drills we want to focus on before playing what is plenty of games." ... The A's signed two 17-year-old free agents from the Dominican Republic, 6-foot-3 right-hander Enmanuel Sullivanand 6-2 right-hander Ruber Aquino.
